.To all whom t may concern I Y Be it known'` that we, GRANviLLE A. HMASON land vVILLIAM VEDWARD LANGLEY, citizens of -the United States, residing at Houstoinfi'n thefcountyof Harris and State of Texas', haveinvented certain new and useful Improvements in- Pumps, of which thefollowing is afspeciiieation.

This invention relates tone'w 'and useful improvements in a pumpand has particular` relation to "an improved form of pump specially adapted foriuse in pumping oil from oilwells; Y

One object of the invention is to provide a? pump of thejcharacter described having an'improvedl form of'plunger,l or traveling valve, which will atia'll times form a close fit in the workingy barrel to preventleakage pastit.` A, l

Another object-of the invention is to pro`T vide, a pump which is so constructed ,that sand will not collect around'the plunger on the` wall 'of the ,working barrel and cause saidplunger to stick inthe working barrel or readily wear away@ f A further feature to provide an improved forin of plunger vspecially conystructed to prevent sand fromcollecting between it and the working barrel and wearing the same out. f@ I v A stil further featureV ofthe invention resides Yin vthe provisionl of ai pump equipped with a conduit through whichfluid may be forced, vunder. pressure, through the standing lvalve `to keep the same cleansed of sand and other detritus. Y. With, thelabove ,andfother objects in view the l.invention has particular relation tocertain-novel features 'of construction, `operav tionfand arrangement of parts, an example Vof which isfg'iven V'11i thisspeciication andv illustrated in the accompanying'drawings, wherein:-, Y Figure 1- is vertical ,sectiona'lfviewof Figure 2;is "a, vertical sectional view, Vvshowing the traveling valvef inthe working barrel. l Y I `Y n Figure isa 'fragmentary vertical sectional view, "showing a modified formiof Figure 4J is af bottom end vj view Y. of the vtraveling valve.

'i Figure '6' is a plaii'new' of an extensible i drawings, the Lnumeral 1 .designatesgthe .65 ,working barrel.` ,Threaded into the lower end of this barrel, by means .of right hand threads, there is a nipple 2-whose upper` end e `is formedvinto avalve seat 3 which iscontrolled by the ball valve 4Q This' valve is,;70

confined bythe cage 5, which is threadedw onto-the upper end of the nipple v2. i, ,The

numeral designates aftubingwhich leads from t-he-toplof the wall down alongside the pumpbarrel and whosel lower end Ais `turned '15 finw'ardlyfthrough said barrel opposite the."

valve.. Fluid, su'ch as fhot steam, air or water, is forced downthrough said tubing,

,underfpressure, against the ball valve which keeps the same washed outandcleansed 0h80 clogging matter, and the pressure `ofsaid fluid through said tubing may VNbe made suilicient to force the oil lor other fluid from the well. In theform shown in Figures l,

f2, 3A andll, aV hollow sucker rod 7 is employed 85 .by means of .which the. traveling lvalve is reciprocated- Vup vand down.` Threaded'onto the lower end ofrtliis sucker rod there is thereducing nipple S'whose lower end is Y reducedfand outwardlyvr threaded'to receive qa() 'the coupling 9 whichfis. threaded thereon. .Inserted through thiscoupling there is, a

tubular' barrel 10.l whose .upper end is threaded through the coupling 9 Vbyiineans pf left-hand threads.v valve seat 11 is L9,5 yfitted intoftheupper end of said barrel` and i is c ontrolledby n ,Y confined within the nipple 8.` Threaded onto the taiwanais whicuis the l0wer,end of theV barrel there yis .i an

elongated clamp nutA 13 and the lower fendfioo Y of the barrel and nut arev 4formedvwith the 'i aligned downwardly extendingv projections 24. Fitted onto therbarrel'l() arethe rings Q15 which are preferably formed ofa suitable 'composition and which are expansible, leach 105 ,ring having AanV internal .annular `rib 16. cen' Ytrally located' with respect to; the' ring. This rib hastransverse slots16 cut therethrough to render the rings moreeasily contracted.

l 0n eachside .ofthisrib there'is a .continueus 110 non-eipansiblev washer 17 preferably formed of leather or some similar material and which atall times fits closely over thefbarrel to prevent fluid from leaking past be- 5 tween the barrel and the rings 15, and each washer is backed by means of an expansiblevrnetal gasket 18,1said gasket lying against the outer sides of the Washer 1*( of the respective rings. A plurality'bffthese'ringsT15 are provided and they are clamped in place between the coupling 9'and the nut 13. In assembling the valve, the Abarrel 10 is threaded through* the" coupling' 9 and `pinned therein by means of the pin`9 and the nipple 8 then v'attached to said coupling.

The rings, with their'washers 'and' gaskets, are thenv fitted over Athe tubular` barrel and clamped closely around said barrel'and held in position by the nut '13 vwhich is screwed '20 'tightly'against' the'lower ring to clamp the rings between it and the coupling'). The vpin9 'holds the barrel against unscrewing from the coupling 9 while the fnut Y13 is being screwed inplace, aterwhich it 'is '"25 removed; The traveling valve' is then let down into theworking barrel,l the projections 14 'ofthe nut 13 and barrel 10 fitting into correspondinggrooves 5V in thek top of the' cage 5. Thesucker rod'isithen ro- '30 tated in a right-hand direction.` The'threads connecting the` barrel Y'10 'with the `coupling 9 being left-hand threads, when the sucker vrod is so rotated they will unscrew, forcing vthe barrel 10 downwardly and carrying `the nut 13 yaway 'from the rings 15, which being released, will suddenly expand and will thereafter tl closely within the working barrel and prevent leakage' pastthem. In lthe form shown in Figure 3, ex'pansible 40 rings 1 9 are provided, which areformed of 'composition material andv are' expansible. These rings are right angular in vcross section and the adjacent Vrings are `reversely arranged,`as shown.` Alternate joints 'are '45 Vbroken by expan'sible Vmetallic bands" 20 on opposite sides lof which are theknonexpanding gaskets' 21", formed of leather or similar material The 'other joints, yarejbroken by non iexpanding leather gaskets 22. Theg'as- $0 kets 21 and' 22 at `'all times lit closelyaround Ethe barrel and.V prevent `leakage' pastlbetween f the same andthe ,'ri'ngsf19` and s aid'v 'gaskets 21- are jbacki-id, on yeac-hv side, by metal washers 23. In the formr shown in Figures lan'd' 8, a hollowV couplingQLrfoi-ms the yage' for the standing valve and I'this coup- "ling is lprovidedl with the u'sualvalvel seat25 "which" is controlled `,byv thel'ballV valve 26. `"Ihis'seat 'is threadedinto the coupling vfrom -"60beneathand-ihasfa polygonal section 27 nto "receive a 'socket wrench. l' Withinlfthis couplingjtherejisian 'annular chamber 28 which "surrundsithe' valve,`fand leadingffroin this "chamber there aref'the 'ducts V29 y which ter- 165 minatewithin Athe valve cage underneath the valve. The tubing 6 enters this chamber and the cleansing Huid is forced under pres 'sure'downthrough the tubing through said chamber and thence through the ducts 29 @against the valve.

-In this form of pump the upper end of lthe standing valve cage is ormedfwith-the projection 30, preferably square 1n cross section," andtheflower end of the travelingvalve has a correspondingly shapedsocket providedto receive saidp'rogection'when it it desired to release the'rings 15, as hereinbefore explained. f l e In 'the form vshown V1n Figure 9, theref'isa tubular unionr31'- threaded on'to this lower vend of the barrel 10 by means of rightehand *threads This union has'` ai plurality of fan-1v -nular peripheralgrooves 324 and its 'lower end yis reduced and threadedint the upper f end of the nippleV by 'means 'otright-hand threads, Landthis' nipple is connected tothe 'upper end of the barrel 34 by v,means of lefthand threads.

In this form the' barrels 10 and 34 halvelthe l rings 15,the washers17 Afand the gaskets 18 as in the form'shownin Figure 1 and'these j are lclamped on'the respectivebarrels by means of the union 31 'and-theclamp ,nut 35, the latter being threaded` onto the r,lower end of th'ebarrel '34. Thisform of plunger has'alsoi the valve seat. 1I at itsupp'erend, controlled by the valve '12' as iin the form shown'in Figure 1. f Any sand a passing be-l tween the upper rings 15 will collecty in'k the i. .s
